I7-930 upgrade to i7-990x?

Not really, because the core architecture performance difference is minimal. Faster video converting and gaming ability will be benefited by a higher end graphics card.

i have two gtx 580 sli and 4 intel SSD in raid 0

There's really no point of upgrading though, you have a system that won't need to be upgraded for another 5 years.

i do not now guys, i am just a little board want to overclock a bit. was thinking to buy a 2011 socket with i7-3930k but ALL my pc water cooled and i just do not want to build it agan. just in over all will i see the difference between 930 4 ghz and 990x 4.6ghz in every day use ? thanks

in everyday use, no.
for media encoding, yes.
gaming, no.
overclocking, yes.

its up to you and if it is worth what you will be paying for it.

Barely any performance difference in media encoding.

Save that money and put it to electric bills.
